LUBRICATOR.

Specification of Letters Patent.

Patented Feb. 13, 1906.

Application led October 12, 1905. Serial No. 282,446.

To all whom it may concern:

Be it known vthat we, JOHN MALOY and ARCHIE WHITE, citizens of theUnited States of America, residing at Dunbar, in the county of Fayetteand State of Pennsylvania, have invented certain new and usefulImprovements in Lubricators, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inlubricators; and the invention relates more particularly to that type oflubricators adapted to automatically feed oil or grease into asteam-line supplying a cylinder or steam-chest.

The primary object of this invention is to provide a novel form ofreceptacle or cup adapted to be connected with a steam-line, the steambeing utilized indirectly to force the contents of the receptacle intothe steamline supplying the steam to the cylinder or steam-chest. Tothis end we have devised a novel form of lubricator in which premeltedgrease or oil is employed as a lubricant and novel means devised forheating and governing the amount of lubricant to be fed to the cylinderor steam-chest.

With the above and other objects in view, which will be more fullyapparent as the nature of the invention is better understood, the sameconsists in the novel construction, combination, and arrangement ofparts to be hereinafter more fully described and then claimed.

Referring to the drawings accompanying this application, like numeralsof reference designate corresponding parts throughout the several views,in which- Figure 1 is a side elevation of our improved lubricator. Fig.2 is a vertical sectional view. Fig. 3 is a vertical transversesectional view of a portion of the same. Fig. /1 is a horizontalsectional view taken on the line a: x of Fig. 1. Fig. 5 is an enlargeddetail sectional view of a valve employed in connection with thelubricator, and Fig. 6 is a similar view of a needle-valve.

To put our invention into practice, we construct our improved lubricatorof a metallic receptacle 1, having cone-shaped ends 2 2.

Passing upwardly through the'receptacle is a pipe 3, said pipe beingthreaded upon its one end, as indicated at 4, and provided with a Tconnection 5 upon its upper end. The receptacle 1 near its bottom isprovided with an opening 6, in which is mounted a conventional form ofglobe-valve 7. Connecting with the globe-valve by means of a union 8 isan1 inverted-U-shaped pipe 9, the opposite end of which connects withthe T 5, thereby forming a circuitous passage for the contents ofthepipe 3 to enter the receptacle 1, the globe-valve 7 controlling theinlet into the receptacle. The receptacle is also provided with anopening 10 near its top, and communicating with said opening is aconventional form of needle-valve 11. The valve supports one end of asight-glass 12, the upper end of the sight-glass being connected to theT 5 by a union connection 14. The needle-valve 11 is provided with adrainage-passage 15, which is controlled by a valve-stem 16, thedrainage-passage 15 being employed to drain the sight-glass at any timedesired.

The bottom of the receptacle 1 is provided with a radiallydisposedenlargement 17, which is drilled to form a bore 18, said borecommunicating with the pipe 3 by an opening 19 and with the interior ofthe receptacle by a port 20. In the bore 13 is mounted a valve-stem 21,which is adapted to control the passage of the contents of the cylinder1 into the pipe 3, the port 20, bore 18, and opening 19 being employedto drain the recepta-` cle of a portion of its contents. The top of thereceptacle 1 is provided with an inletport 22, and controlling this portis a conventional form of valve 23.

When our improved lubricator is to be used, the pipe 3 is adapted to betapped into a steam-line which supplies the receptacle or asteam-chest.Thepassageefsteamthrough the pipe 3 into the receptacle 1 is controlledby the valve 7, and we will assume that the valve is open and steam ispassing into said receptacle. The lubricant to be used in connectionwith our improved lubricator is placed in the receptacle 1 through thevalve 23, and then said valve is closed. The admission of steam to thereceptacle 1 will maintain the lubricant in a fluid state, heating thesame and preventing it from freezing or clogging the ports of thecylinder. The condensed water from the steam iioats the lubricantupwardly, and a portion of said lubricant and steam passes through theopening 1() into the needle-valve 11. This valve is adapted to admitcertain quantities of lubricant to the sight-glass 12, from whence thesteam forces the same upwardly into the T connection 5, and thelubricant passing through the sight-glass is fed into the pipe 3 IOO IIO

vthe amount of lubricant being ejected from .the receptacle dependingentirely upon the surface or size of cylinder to be lubricated.

The sight-tube 12 during the operation of the lubricator is partiallyfilled with water,'

which results from the condensation of steam and the oil or otherlubricant rises through this water and {ioats on top thereof. The eX-cess of water is drained off through the drainage-passage 11 and thevalve-stem 16 is utilized to regulate the rate at which the water willbe allowed to escape.

When the lubricator is to be placed out of operation, the valve-stem 16is manipulated to entirely drain the sight-glass 12 and the valvev 21 ismanipulated to drain the receptacle 1, and thereby prevent the lubricantfrom becoming solidified or frozen within the sightglass or receptacle.It will be noted that the grease or lubricant used in connection withour improved lubricator is maintained in a iuid state or conditionduring the operation of the lubricator and that the same can be easilyand quickly regulated to feed various quantities of lubricant to thecylinder or steam-chest to be oiled.

What we claim, and desire to secure by Letters Patent, is-

1. In a lubricator the combination of a cylindrical receptacle, asteam.- pipe passing centrally through said receptacle, aninverted-U-shaped pipe connected to the upper end of said steam-pipe,one leg of said U- shaped pipe extending downwardly alongside saidreceptacle, a globe-valve connected to the lower end of said leg, saidglobe-valve being connected with said receptacle, a needle-valve carriedby said receptacle, a sightglass carried by the receptacle and providedwith a drainage-passage, a valvestem controlling said drainage-passage,said sightglass being in communication with said U- shaped pipe abovethe upper end of said steam-pipe.

2. In a lubricator the combination with a cylindrical receptacle, of asteam-pipe passing centrally through said receptacle, said receptaclebeing provided with a radiallydisposed enlargement on its bottom, saidenlargement having a bore communicating with said steam-pipe and withthe interior of the receptacle, a valve-stem adapted to control thepassage through said bore, a pipe leading from the upper end of saidsteampipe to the lower end of the receptacle, a globe-valve on saidpipe, a needle-valve mounted on the receptacle, and a sight-glassmounted on said receptacle and communieating with the last-named pipe.

3. In a sight-feed lubricator the combination with a receptacle and apipe passing therethrough, of a U-shaped pipe connected to thefirst-named pipe above the top of the receptacle, one end of saidU-shaped pipe eX- tending downwardly to and communicating with the lowerend of the receptacle, a needle-valve carried by the receptacle and asight-glass mounted on said receptacle and communicating with saidU-shaped pipe.

In testimony whereof we affix our signatures in the presence of twowitnesses.
